© 2020, Springer Science+Business Media, LLC, part of Springer Nature.Data on the waviness of a processed part related to the coordinate system associated with the laser treatment bench used with a surface are needed to increase the effectiveness of the technology of laser destructuring. At the present time, there are no contactless topographic measurement instruments that meet all the requirements that are imposed on the system used in measurement of the profile of the surface of parts and that are determined by the parameters of the technological process of laser destructuring. A trial design of a system for measurement of the profile of a surface (waviness) constructed according to the principle of an optical profilometer and modified in accordance with the requirements imposed on measurements performed on a laser treatment bench is created. Through the use of the system measurements of waviness are performed directly on the bench, which significantly reduces the length and difficulty of the technological process. A diagram and operating principle of the waviness measurement system on a laser destructing bench are described. A triangulation method is used in the measurements. Through the use of a trial design of the system the waviness profi le of a surface with spatial wavelength 2 mm may be measured with error 3.78 μm in the vertical direction and 13.8 μm in the lateral direction. Verification of the precision of the trial design of the system is performed by a standard method of stylus profilometry. The waviness profile of a surface obtained with the use of the trial design of the system may be used for modulation of the amplitude of the power of laser radiation in hte technological process of laser destructuring.
